About the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X90X60
The AirTAC SCT100X90X60 is a double-acting multi-position cylinder that provides four distinct, repeatable rod positions: 0 mm (fully retracted), 90 mm, 60 mm, and a total extended length of 150 mm. This is achieved by independently pressurizing two piston sections on a common rod line, each delivering a powerful 3927 N of push force at 0.5 MPa. The cylinder features a robust 25 mm diameter rod and PT1/2 ports, with a body length A of 308 mm.
With a 29 mm adjustable air cushion on each section, the SCT100X90X60 decelerates loads smoothly at both end-of-stroke positions, protecting the cylinder and tooling. The tie-rod construction ensures durability in demanding industrial settings. At the maximum operating pressure of 1.0 MPa, a single section can generate up to 801 kgf of theoretical thrust, making it suitable for heavy-duty sorting, diverting, or multi-stop pressing tasks.

| Model | Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X90X60 |
|---|---|
| Series | SCT multi-position tie-rod cylinder |
| Bore size | Ø100 mm |
| Stroke 1 / Stroke 2 | 90 / 60 mm |
| Total travel | 150 mm |
| Stop positions | 4 positions |
| Acting type | Double acting (tandem, multi-position) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 29 mm |
| Max stroke / section | Up to 500 mm standard |
Specifications follow the official AirTAC SCT (multi-position) datasheet. SCT is available in bores 32–100; each of the two sections has a 500 mm max standard stroke (800 mm max). Confirm against the product label before installation. Thread options: PT (standard) / G.
Stop Positions (4)
| Position | Rod extension |
|---|---|
| P0 (retracted) | 0 mm |
| P1 (section 1) | 90 mm |
| P2 (section 2) | 60 mm |
| P3 (both extended) | 150 mm |
Positions are set by pressurising section 1, section 2, or both. With equal strokes you get 3 distinct positions; with unequal strokes you get 4.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
Force is per actuated piston section (single-piston, same as the SC bore): push uses the full bore area, pull subtracts the rod area. Size with a safety margin.

Where the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X90X60 Is Used
Four-Way Sorting Gate
Direct packages or components to four distinct lanes or chutes by commanding the rod to the 0, 60, 90, or 150 mm positions, simplifying conveyor line routing with a single actuator.
Two-Depth Pressing Station
Perform a shallow 60 mm pre-press operation followed by a full 90 mm insertion stroke, or combine both for a 150 mm deep-set action, all with one compact tandem cylinder.
Multi-Stop Part Feeding
Advance parts in a feeder track to three precise stop points for sequential drilling, inspection, and ejection, using the discrete 60, 90, and 150 mm positions.
Is the Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X90X60 the Right Cylinder?
Select the SCT100X90X60 when your application requires a compact, self-contained actuator to index between four fixed positions without the complexity of two separate cylinders and external stops. This model is ideal for replacing a setup that previously used two individual cylinders to achieve a 90 mm and a 60 mm stroke. For a direct replacement, ensure the new unit matches the 100 mm bore, both 90 mm and 60 mm strokes, PT port thread, and basic mounting style. If your force requirements are lower, consider stepping down to the 80 mm bore SCT, which provides 2513 N of push force per section at 0.5 MPa.
Multi-position checklist
- ✓ Need 4 repeatable stops?
- ✓ Section strokes 90 + 60 mm suit your layout?
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Plumb the two sections to the correct valves for each stop.
- check Adjust end cushion screws for smooth stops.
- check Use SCT mounting accessory (FA / FB / CA / CB / LB).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCT80~100 Multi-Position Tandem Cylinder SCT100X90X60 FAQ
The four discrete rod positions are 0 mm (fully retracted), 90 mm (first section extended), 60 mm (second section extended), and 150 mm (both sections extended). These are fixed by the two stroke lengths and are selected by pressurizing the cylinder's sections individually or together.
The SCT100X90X60 integrates two strokes into one tie-rod body, guaranteeing alignment and saving space versus mounting two SC100 cylinders back-to-back. It eliminates the need for external coupling hardware and ensures the four stop positions are mechanically fixed relative to each other, simplifying setup and improving repeatability.
